RSS auto-discovery is a way that makes it possible for web browsers and services to automatically detect a blog's RSS. It's also a way to inform blog readers that they can follow blog's updates easily via a syndication feed. To learn more about how RSS works, please check this link.
Usually blog platforms enable blog feeds automatically, so that blog readers can follow blogs via RSS updates, as well as services that rely on blog feeds can function properly.
If RSS auto-discovery is not enabled, normally you'll get an alert that your blog doesn't have an RSS while you submit your blog with us. You should be able to find options to enable feeds in your blog control panel. Here's how to enable RSS for *blogspot.com blogs:
• Log in to blogger.com and click on "Settings" and then "Other";
• Look for "Site Feed" section and make sure that "Allow Blog Feed" is not set to "None".
Alternatively, enabling RSS can be done manually by adding a simple line of code in the header of the blog, referring the RSS feed of the blog. The following line of code should be added somewhere between
</head>tags in blog's html:
<link rel="alternate" type="application/rss+xml" title="TITLE" href="RSS-URL" />
RSS-URLaccordingly to point to the RSS of your blog.
Completing the above, should fix eventual issues you might have submitting your blog to BlogUpp or other services. Note as well that empty RSS post titles prevent us from making use of your blog posts in order to promote the blog. If that is your case - please consider adding titles and then resubmit.
